The WL900 Radar Level Transmitters offer a logical extension to ultrasonic
devices, where application conditions are in need of non-contact liquid level
measurement but ultrasonic level transmitter measurement is not
acceptable. The WL900 Radar Level Transmitters are ideal for a variety of
water and wastewater applications where you have a reflective liquid that has a
foaming surface, vapors, or dusty conditions beyond ultrasonic transmitter
capabilities. The Radar Level Transmitters are also unaffected by
temperature, vacuums, pressure, methane, or CO2.

The WL900 Radar Level Transmitters use state-of-the-art radar pulse technology
which provide accurate and reliable level measurements over their wide 10 inch
to 50 foot range. With their simple push-button calibration system, the
WL900 Radar Level Transmitters are easy to set up and maintain on the bench or
in the field by following simple instructions. Simply aim the WL900 Radar
Level Transmitters at your low range level set point and push the button to
lock in the setting - do the same with the high level set point. This may
be done before permanently installing the Radar Level Transmitter by aiming the
instrument at a wall and using a tape measure to determine your exact range.

WL400 Water Level Sensor
When ordering, specify water level range that will cover the maximum water
level change for your application (this is not necessarily the total depth of
water): 0-3, 0-15, 0-30, 0-60, 0-120, 0-250, 0-500 ft. Selecting the
smallest water level range possible will ensure the greatest accuracy.
Includes 25 feet of cable.
